Product Schema
Product structured data that exposes price, availability, reviews, and offers.
Definition
Product Schema describes a sellable item with structured attributes such as name, image, brand, SKU, GTIN, price, availability, reviews, shipping, and returns.
Why It Matters
AI shopping agents need reliable product facts before they can compare, recommend, or transact.
How AI Uses It
AI can extract product identity, eligibility, price, inventory, and differentiators without relying only on page copy.
Commerce Example
A skincare PDP exposes GTIN, ingredients, size, price, availability, aggregateRating, shippingDetails, and return policy.

Common Data Gaps
| Gap | Why AI Struggles | Fix |
|---|---|---|
| No GTIN or SKU | Identity matching is weaker. | Map catalog IDs into markup. |
| Price differs from page | AI may distrust the offer. | Use a single source of truth. |
| Missing variant data | Agents cannot recommend exact SKUs. | Mark each variant offer distinctly. |
